Abstract

Water hardenable splinting bandages comprising a flexible fabric carrying an isocyanate terminated prepolymer having a reaction functionality of not less than two and a catalyst which bandage is characterised in that the prepo-Iymer is a water absorbing isocyanate terminated prepolymer and the catalyst is water soluble but insoluble in the prepolymer, compositions therefore and processes of manufacture thereof are described.
